The researchers found that for muscles to grow following exercise, according to new a September 27, 2021 article In Medical Express written by The Physiological Society. Based on a study of mice, the gut microbiome may be important for the health of our muscles.

The study found that the mice that received antibiotic treatment which killed the bacteria of their gut microbiome showed significantly less muscle growth than mice who did not receive the antibiotic treatment.

John McCarthy, senior author added “world-class runners were found to have more of a particular type of bacteria that provided an additional source of energy which was thought to help them run faster. Thus, the gut microbiome makes substances that appear to be important for skeletal muscles,” he is quoted saying in the Medical Express report.

The microbiome of corals -- which comprise bacteria, fungi and viruses -- play an important role in the ability of corals to tolerate rising ocean temperatures, according to a September 30 2021 article in Science Daily led by Penn State University. Says Penn State biology professor Monica Medina, prolonged exposure to heat can cause 'bleaching' and the animal to die.

Viridiana Avila-Magaña, former student at Penn State, and team tracked genes that have already diverged in expression across species in response to any given stimuli -- in our case heat stress. She is currently a postdoctoral fellow at Colorado University Boulder.

The entire holobiont -- the coral animal, photosymbiont and microbiome -- is involved in the stress response. They found several genes that aid a coral’s response to heat stress. They also found more tolerant species had greater bacterial activity and diversity, according to Science Daily. The microbiome includes bacteria, fungi and viruses.

Among the three coral species examined - mountainous star coral, the knobby brain coral, and the starlet coral - the starlet coral was found to be more heat stress tolerant. This is due in part to a higher number and diversity of thermally tolerant microbes in their microbiomes, according to the Science Daily article.

According to a September 22 2021 article in Healio, Bifidobacterium animalis subsp. lactis BB-12 in yogurt may protect patients against harmful changes in the gut microbiome as first reported in Nutrients.

“ If one picks a well proven probiotic, they can expect to see important changes such as short chain fatty acid and microbiome protection,” Daniel Merenstein, MD, from the department of family medicine, Georgetown University Medical Center, told Healio Gastroenterology. Dr. Merenstein based this on a 7 - day study of 42 patients, measuring “fecal levels of short-chain fatty acid and bacterial composition”.

In a September 16 2021 Science Focus report, Seattle’s Institute for Systems Biology lead author Dr Christian Diener is quoted saying “your gut microbiome can help or cause resistance to weight loss and this opens up the possibility to try to alter the gut microbiome to impact weight loss.”

Dr. Diener’s assertions are based on a study of 5,000 dieters with a focus of 105 individuals and a control group, collecting blood and stool samples from the participants, and studying their genetic material. The study found that specific gut bacteria in each group were resistant, while others supported weight loss. In the Science Focus article, Dr. Diener concludes that “the gut microbiome is a major player in modulating whether a weight loss intervention will have success or not.”

Common medications can accumulate in gut bacteria, says a new study reported September 08 2021 in Medical Express. Research on the subject was conducted by Medical Research Council (MRC) Toxicology Unit at the University of Cambridge and the European Molecular Biology Laboratory (EMBL) in Germany. The building up of drugs in our gut bacteria can alter bacterial function and reduce the drug’s effectiveness.

15 common drugs were combined and tested with 25 different gut bacteria to see how they interacted. The researchers found that the drug accumulated in the gut bacteria demonstrated some signs of reduction in the availability of the drug to the rest of the human body. It is believed that the accumulation altered bacterial function, believed to be linked to side-effects. The research was first reported in Nature.

According to an August 4 2021 Sci Tech Daily tryptophan is an essential amino acid for your microbiome gut health. Tryptophan is known to aid in the creation of the neurotransmitter serotonin and melatonin. Tryptophan is commonly found in milk, turkey, chicken, and oats. A deficiency of tryptophan led to a threefold increase in the bacterium Acetatifactor, and significant reductions of Mucispirillum and Blautia, concludes the author’s study.

This is first reported by Dr. Sadanand Fulzele, an aging researcher in the Medical College of Georgia Department of Medicine, first published in the International Journal of Molecular Sciences.

An August 03 2021 article in the Scientific American interviews what they call the first Astromycologist Paul Stamets along with other research teams who are studying how fungi can be leveraged to build extraterrestrial habitats and perhaps someday even terraform planets.

Stamets says plants need minerals, and “pairing fungi up with plants and debris from humans [causes them to] decompose into a form that then creates rich soils that could help generate the foods that astronauts need.” Stamets has identified oyster mushrooms as one of the best species of mushrooms that is able to breakdown regolith, or asteroid dust so far.

According to the Scientific American article, Stamets says that oyster mushrooms are particularly adept at breaking down hydrocarbons and dismantling them, then restructure them into fungal carbohydrates, or sugars. It is possible he says to feed the mushrooms certain nutritional supplements which create a catalytic reaction, which in turn creates more biodiversity.

This study steps outside the wealthy regions of Europe and North America to lower income countries such as Fiji and Guatemala with their gut microbiome research.

As reported in Medical Express’ July 28 2021 issue by Cornell’s David Nutt, Ilana Brito, Cornell assistant professor and the Mong Family Sesquicentennial Faculty Fellow in Biomedical Engineering in the College of Engineering, and her team took microbiome samples from the three global populations and put them in 30 germ-free mice to study immune responses to intestinal infections. Microbial differences among these populations proved to show the varying degrees of response. Researchers also found that “housing the mice together so that they shared microbiota helped mice with low resistance to infection become more resilient”, according to the Medical Express report. The less resilient mice benefited from the sharing of microbiota.

Brito and her team found that Guatemala microbiota proved most resistant, followed by the U.S., then Fiji, according to the Medical Express report where she is quoted, "The interesting thing was they are exhibiting these differences in resilience to infection in a very short time.” This points to a possible health remedy through sharing microbiota across regions of the world.

A July 08 2021report by Medical Express at the University of Notre Dame found that most bacteria in the gut microbiome of baboons are heritable after looking at more than 16,000 gut microbiome profiles collected over 14 years. from a long-studied population of baboons in Kenya's Amboseli National Park.

“This moves us away from the idea that genes play very little role in the microbiome to the idea that genes play a pervasive, if small, role," said Elizabeth Archie, professor in the Department of Biological Sciences, she is quoted in Medical Express.

The researchers used fecal samples from 585 wild Amboseli baboons, typically with more than 20 samples per animal, including microbiome variations in the baboons' diets between wet and dry seasons. The result of this study showed that gut microbiome is 97% heritable.
